Diamond Drilling Resumes on the Sandra Silver-Gold Project in Durango, Mexico

VANCOUVER, BC, June 22, 2022 /PRNewswire/ - Orex Minerals Inc. – (TSXV: REX) (OTCQB: ORMNF) ("Orex") is pleased to announce the resumption of diamond drilling on the Sandra Silver-Gold Project in northwestern Durango State, Mexico. This is a joint venture between Pan American Silver Corp. (60%) and Orex Minerals Inc. (40%). Phase-I of this new drilling program will consist of approximately 2,500 to 3,000 metres.

Orex's President & CEO, Ben Whiting, P.Geo., states: "It is always exciting to start a new phase of exploration and diamond drilling is one of the most important steps. We and our joint venture partners look forward to advancing the Sandra Silver-Gold Project." 

The drilling contract has been awarded to Globexplore, an experienced diamond drilling service company, utilizing low environmental impact, man-portable drill rigs. Globexplore has an excellent environmental, community and safety record in Mexico.

Throughout 2021 and into early 2022, Orex conducted a geological mapping and lithogeochemical sampling program over the combined 6,970 hectares of the Project. This program was carried out under strict COVID-19 safety protocols and was assisted by the consulting group Geotech Evaluation Services ("GES"), who will also be assisting on this new drilling program.

To date, there have been two drilling programs on the Sandra Project. The 2011 program consisted of 11 exploratory holes for 1,849 metres and the 2015-2016 program consisted of 65 exploratory and resource definition holes for 9,821 metres, which lead to the identification of the Boleras Silver Deposit in the southeast sector. There are multiple, untested drill targets identified on the property.

Sandra is situated north of the town of Tepehuanes, Durango, in the heart of the "Mexican Silver Trend", midway between the mining districts of Tovar and Guanacevi. It is also 75 km west of Endeavour Silver's La Pitarrilla deposit. This prolific trend hosts some of the World's largest silver camps and deposits, including Fresnillo, Guanajuato, La Pitarrilla, La Preciosa, Real de Angeles and Zacatecas. (Mineralization hosted on adjacent and/or nearby properties is not necessarily indicative of mineralization hosted on the Sandra Property.)

The Project covers almost 70 square kilometres of contiguous mineral concessions and includes multiple mineralized epithermal quartz veins, disseminated horizons and breccia structures. These mineralized features form a high-level silver-gold-base metals system, hosted in andesitic and rhyolitic rocks, centered on a large rhyolite dome complex in the north, intrusive related vein systems to the west, and silver-bearing systems in smaller rhyolite dome complexes to the southeast. Intense alteration zones and fluid flooding in permeable formations indicates the presence of bulk tonnage targets.

An initial mineral resource estimate at Sandra was released in 2016 for the disseminated silver discovery of the Boleras Deposit. Located at surface in the southeastern part of the Project, the Boleras Deposit contains an Inferred Resource Estimate of 9.8 million tonnes, grading 106 g/t Ag, for a total of 33.3 million ounces of silver (see news release 31 October 2016).

Excellent infrastructure exists in the Sandra area, including paved road access, electrical power, water and manpower from nearby communities. Community engagement is an important part of the ongoing Environmental, Social and Governance (ESG) efforts.
